Evolution of the ventricles. (1/130)

We studied the evolution of ventricles by macroscopic examination of the hearts of marine cartilaginous and bony fish, and by angiocardiography and gross examination of the hearts of air-breathing freshwater fish, frogs, turtles, snakes, and crocodiles. A right-sided, thin-walled ventricular lumen is seen in the fish, frog, turtle, and snake. In fish, there is external symmetry of the ventricle, internal asymmetry, and a thick-walled left ventricle with a small inlet chamber. In animals such as frogs, turtles, and snakes, the left ventricle exists as a small-cavitied contractile sponge. The high pressure generated by this spongy left ventricle, the direction of the jet, the ventriculoarterial orientation, and the bulbar spiral valve in the frog help to separate the systemic and pulmonary circulations. In the crocodile, the right aorta is connected to the left ventricle, and there is a complete interventricular septum and an improved left ventricular lumen when compared with turtles and snakes. The heart is housed in a rigid pericardial cavity in the shark, possibly to protect it from changing underwater pressure. The pericardial cavity in various species permits movements of the heart-which vary depending on the ventriculoarterial orientation and need for the ventricle to generate torque or spin on the ejected blood- that favor run-off into the appropriate arteries and their branches. In the lower species, it is not clear whether the spongy myocardium contributes to myocardial oxygenation. In human beings, spongy myocardium constitutes a rare form of congenital heart disease.  (+info)

Chordate evolution and the origin of craniates: an old brain in a new head. (2/130)

The earliest craniates achieved a unique condition among bilaterally symmetrical animals: they possessed enlarged, elaborated brains with paired sense organs and unique derivatives of neural crest and placodal tissues, including peripheral sensory ganglia, visceral arches, and head skeleton. The craniate sister taxon, cephalochordates, has rostral portions of the neuraxis that are homologous to some of the major divisions of craniate brains. Moreover, recent data indicate that many genes involved in patterning the nervous system are common to all bilaterally symmetrical animals and have been inherited from a common ancestor. Craniates, thus, have an "old" brain in a new head, due to re-expression of these anciently acquired genes. The transition to the craniate brain from a cephalochordate-like ancestral form may have involved a mediolateral shift in expression of the genes that specify nervous system development from various parts of the ectoderm. It is suggested here that the transition was sequential. The first step involved the presence of paired, lateral eyes, elaboration of the alar plate, and enhancement of the descending visual pathway to brainstem motor centers. Subsequently, this central visual pathway served as a template for the additional sensory systems that were elaborated and/or augmented with the "bloom" of migratory neural crest and placodes. This model accounts for the marked uniformity of pattern across central sensory pathways and for the lack of any neural crest-placode cranial nerve for either the diencephalon or mesencephalon.

Evolution of the basal ganglia: new perspectives through a comparative approach. (3/130)

The basal ganglia (BG) have received much attention during the last 3 decades mainly because of their clinical relevance. Our understanding of their structure, organisation and function in terms of chemoarchitecture, compartmentalisation, connections and receptor localisation has increased equally. Most of the research has been focused on the mammalian BG, but a considerable number of studies have been carried out in nonmammalian vertebrates, in particular reptiles and birds. The BG of the latter 2 classes of vertebrates, which together with mammals constitute the amniotic vertebrates, have been thoroughly studied by means of tract-tracing and immunohistochemical techniques. The terminology used for amniotic BG structures has frequently been adopted to indicate putative corresponding structures in the brain of anamniotes, i.e. amphibians and fishes, but data for such a comparison were, until recently, almost totally lacking. It has been proposed several times that the occurrence of well developed BG structures probably constitutes a landmark in the anamniote-amniote transition. However, our recent studies of connections, chemoarchitecture and development of the basal forebrain of amphibians have revealed that tetrapod vertebrates share a common pattern of BG organisation. This pattern includes the existence of dorsal and ventral striatopallidal systems, reciprocal connections between the striatopallidal complex and the diencephalic and mesencephalic basal plate (striatonigral and nigrostriatal projections), and descending pathways from the striatopallidal system to the midbrain tectum and reticular formation. The connectional similarities are paralleled by similarities in the distribution of chemical markers of striatal and pallidal structures such as dopamine, substance P and enkephalin, as well as by similarities in development and expression of homeobox genes. On the other hand, a major evolutionary trend is the progressive involvement of the cortex in the processing of the thalamic sensory information relayed to the BG of tetrapods. By using the comparative approach, new insights have been gained with respect to certain features of the BG of vertebrates in general, such as the segmental organisation of the midbrain dopaminergic cell groups, the occurrence of large numbers of dopaminergic cell bodies within the telencephalon itself and the variability in, among others, connectivity and chemoarchitecture. However, the intriguing question whether the basal forebrain organisation of nontetrapods differs essentially from that observed in tetrapods still needs to be answered.  (+info)

Soft-tissue anatomy of the extant hominoids: a review and phylogenetic analysis. (5/130)

This paper reports the results of a literature search for information about the soft-tissue anatomy of the extant non-human hominoid genera, Pan, Gorilla, Pongo and Hylobates, together with the results of a phylogenetic analysis of these data plus comparable data for Homo. Information on the four extant non-human hominoid genera was located for 240 out of the 1783 soft-tissue structures listed in the Nomina Anatomica. Numerically these data are biased so that information about some systems (e.g. muscles) and some regions (e.g. the forelimb) are over-represented, whereas other systems and regions (e.g. the veins and the lymphatics of the vascular system, the head region) are either under-represented or not represented at all. Screening to ensure that the data were suitable for use in a phylogenetic analysis reduced the number of eligible soft-tissue structures to 171. These data, together with comparable data for modern humans, were converted into discontinuous character states suitable for phylogenetic analysis and then used to construct a taxon-by-character matrix. This matrix was used in two tests of the hypothesis that soft-tissue characters can be relied upon to reconstruct hominoid phylogenetic relationships. In the first, parsimony analysis was used to identify cladograms requiring the smallest number of character state changes. In the second, the phylogenetic bootstrap was used to determine the confidence intervals of the most parsimonious clades. The parsimony analysis yielded a single most parsimonious cladogram that matched the molecular cladogram. Similarly the bootstrap analysis yielded clades that were compatible with the molecular cladogram; a (Homo, Pan) clade was supported by 95% of the replicates, and a (Gorilla, Pan, Homo) clade by 96%. These are the first hominoid morphological data to provide statistically significant support for the clades favoured by the molecular evidence.  (+info)

Evolution of the structure and function of the vertebrate tongue. (6/130)

Studies of the comparative morphology of the tongues of living vertebrates have revealed how variations in the morphology and function of the organ might be related to evolutional events. The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. This review examines the fundamental importance of morphology in the evolution of the vertebrate tongue, focusing on the origin of the tongue and on the relationship between morphology and environmental conditions. Tongues of various extant vertebrates, including those of amphibians, reptiles, birds and mammals, were analysed in terms of gross anatomy and microanatomy by light microscopy and by scanning and transmission electron microscopy. Comparisons of tongue morphology revealed a relationship between changes in the appearance of the tongue and changes in habitat, from a freshwater environment to a terrestrial environment, as well as a relationship between the extent of keratinization of the lingual epithelium and the transition from a moist or wet environment to a dry environment. The lingual epithelium of amphibians is devoid of keratinization while that of reptilians is keratinized to different extents. Reptiles live in a variety of habitats, from seawater to regions of high temperature and very high or very low humidity. Keratinization of the lingual epithelium is considered to have been acquired concomitantly with the evolution of amniotes. The variations in the extent of keratinization of the lingual epithelium, which is observed between various amniotes, appear to be secondary, reflecting the environmental conditions of different species.  (+info)

FINE STRUCTURE OF THE PINEAL ORGANS OF THE ADULT FROG, RANA PIPIENS. (8/130)

Frontal organs and epiphyses of the pineal system from the adult frog, Rana pipiens, were fixed in s-collidine-buffered osmium tetroxide, embedded in Epon 812, and examined by electron microscopy. Epiphyseal material was also fixed in a variety of ways and subjected to a series of cytochemical tests for light microscopy. An ultrastructure resembling that of lateral eye retina is confirmed in this species. Photoreceptor cells of the epiphysis and frontal organ display many cytological features similar to those of retinal rods and cones in the arrangement of their outer and inner segments and synaptic components. However, in these pineal organs the outer segments are disoriented relative to each other and may display a disarranged internal organization unlike normal retinal photoreceptors. Furthermore, other pineal outer segments often appear degenerate. Since immature stages in the development of new outer segments also appear to be present, adult pineal photoreceptors are probably engaged in a constant renewal of outer segment membranes. The evidence further suggests that macrophages are involved in phagocytosis of degenerated outer segments. Postulated photoreceptor activities and the possibility of secondary pineal functions, such as secretion, are discussed in view of current morphological and cytochemical findings.  (+info)

This thesis describes the implementation of an interface for querying established correspondences between anatomical structures across species. I was the main developer of this query engine, called the Comparative Anatomy Information System. My work involved developing methods to query the knowledge base, perform the specified comparison, display the anatomical hierarchies and results, and implement features to make the application user-friendly. The comparisons are based on the Structural Difference Method (SDM) for finding similarities and differences, developed in previous work. Since the CAIS knowledge base is sparsely populated, it has thus far been difficult to conduct extensive user testing, but I include two usage scenarios proposed by one of my mentors that outline some proposed uses of the application. These scenarios reflect the need for a system like CAIS that communicates anatomical correspondences to researchers who work on animal modeling of disease with a background other than ...

Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny (the evolution of species). Comparative anatomy has long served as evidence for evolution, now joined in that role by comparative genomics; it indicates that various organisms share a common ancestor. Also, it assists scientists in classifying organisms based on similar characteristics of their anatomical structures. A common example of comparative anatomy is the similar bone structures in forelimbs of cats, whales, bats, and humans. All of these appendages consist of the same basic parts; yet, they serve completely different functions. The skeletal parts which form a structure used for swimming, such as a fin, would not be ideal to form a wing, which is better-suited for flight. One explanation for the forelimbs similar composition is descent with modification. Through random mutations and natural selection, each organisms anatomical ...

A number of shelled and shell-less gastropods are known to use multiple defensive mechanisms, including internally generated or externally obtained biochemically active compounds and structures. Within Nudipleura, nudibranchs within Cladobranchia possess such a special defense: the ability to sequester cnidarian nematocysts - small capsules that can inject venom into the tissues of other organisms. This ability is distributed across roughly 600 species within Cladobranchia, and many questions still remain in regard to the comparative morphology and evolution of the cnidosac - the structure that houses sequestered nematocysts (called kleptocnides). In this paper, we describe cnidosac morphology across the main groups of Cladobranchia in which it occurs, and place variation in its structure in a phylogenetic context to better understand the evolution of nematocyst sequestration. Overall, we find that the length, size and structure of the entrance to the cnidosac varies more than expected based on previous

The morphology of the lower jaw and teeth of the legless lizard Pseudopus apodus (Anguimorpha, Anguidae, Anguinae) from Eurasia are described in detail and compared with those of other species of the subfamily Anguinae. The lower jaw anatomy of Pseudopus, especially the dentary and teeth, clearly differs from the genera Ophisaurus and Anguis. Even so, Ophisaurus is largely uniform in its lower jaw morphology across species. The teeth of North American Ophisaurus are slender cylinders, the shafts are mesiodistally compressed and bulge lingually; the apices are curved lingually and posteriorly and have weakly developed cutting edges. Southeast Asian and North African Ophisaurus present conical teeth, with broadened bases, apices more distinctly curved lingually and posteriorly, and cutting edges that are distinctly developed. The lingual surfaces of the tooth apices are striated in Ophisaurus and Pseudopus. The lower jaw of Ophisaurus is in many respects similar to that in Anguis, however, the ...

Although these animals differ in the types and numbers of teeth they possess, the various kinds of teeth when present, share common structural features. The incisors are broad, flattened and spade-like. Canines may be small as in horses, prominent as in hippos, pigs and some primates (these are thought to be used for ...

The generation of phagocytic cups and immunological synapses are crucial events of the innate and adaptive immune responses, respectively. They are triggered by distinct immune receptors and performed by different cell types. However, growing experimental evidence shows that a very close series of molecular and cellular events control these two processes. Thus, the tight and dynamic interplay between receptor signaling, actin and microtubule cytoskeleton, and targeted vesicle traffic are all critical features to build functional phagosomes and immunological synapses. Interestingly, both phagocytic cups and immunological synapses display particular spatial and temporal patterns of receptors and signaling molecules, leading to the notion of phagocytic synapse. Here, we discuss both types of structures, their organization, and the mechanisms by which they are generated and regulated.

Evidence on their evolution comes from comparative anatomy, the fossil record and molecular biology. It is thought that the first passerines evolved in the southern continent of Gondwana in the Palaeogene, maybe around the Upper Palaeocene some 60-55 mya.[5][6] The early fossil record is poor because the first Passeriformes were on the small side, and their delicate bones did not preserve well. Two specimens from Queensland, Australia are fossil bone fragments clearly recognizable as passeriform. They are two species of about 10 and 20 cm in overall length. This proves that some 55 mya, barely into the early Eocene, early perching birds were recognizably distinct.[7] It also suggests that the origin of this great order of birds was in the southern continent. ...
A quick divergence from my usual dinosaurs, and I shall talk about big cats today. This is because to my greatest delight, I had discovered today a wonderful book. It is called The Felidæ of Rancho La Brea (Merriam and Stock 1932, Carnegie Institution of Washington publication, no. 422). As the title suggests it goes into details of felids from the Rancho La Brea, in particular Smilodon californicus (probably synonymous with S. fatalis), but also the American Cave Lion, Panthera atrox. The book is full of detailed descriptions, numerous measurements and beautiful figures. However, what really got me excited was, in their description and comparative anatomy of P. atrox, Merriam and Stock (1932) provide identification criteria for the Lion and Tiger, a translation of the one devised by the French palaeontologist Marcelin Boule in 1906. I have forever been looking for a set of rules for identifying lions and tigers and ultimately had to come up with a set of my own with a lot of help fro ...

The larynx () is a musculocartilaginous organ guarding the entrance to the trachea, which serves as an air passageway, aids vocalization, and prevents the inspiration of foreign material. The valvular function of the larynx, by means of the epiglottis, is vital, because it is across its inlet that all substances swallowed must pass in their course from the oral pharynx through the laryngeal pharynx to the esophagus. Negus (1949) has described and illustrated the comparative anatomy of the larynx from fish through mammals, and Piérard (1965) studied the dog and other carnivores. The larynx is located directly caudal to the root of the tongue, oral pharynx, and the soft palate, ventral to the atlas. It is approximately 6 cm long in a medium-sized dog, nearly half of this length being occupied by the epiglottic cartilage, which lies at the laryngeal opening. The intrinsic muscles of the larynx control the size of the laryngeal inlet, the size and shape of the glottis, and the positions of the ...

Dr William Charles Osman Hill FRSE FZS FLS FRAI (13 July 1901 - 25 January 1975) was a British anatomist, primatologist, and a leading authority on primate anatomy during the 20th century. He is best known for his nearly completed eight-volume series, Primates: Comparative Anatomy and Taxonomy, which covered all living and extinct primates known at the time in full detail and contained illustrations created by his wife, Yvonne. Schooled at King Edward VI Camp Hill School for Boys in Birmingham and University of Birmingham, he went on to publish 248 works and accumulated a vast collection of primate specimens that are now stored at the Royal College of Surgeons of England.

PLATTEVILLE-Its a case where the dead teach the living. University of Wisconsin-Platteville biology majors and pre-professional students are learning more about the human body than textbooks or models could possibly provide. Four cadavers, two of each gender, are providing practical experience in Russell Hall.. Eight UWP students are doing independent study dissecting the cadavers this semester under the tutelage of biology department chair Wayne Weber and Amanda Trewin, assistant professor of biology.. This is a unique opportunity that will help students work in greater depth, said Trewin, who teaches anatomy and physiology and comparative anatomy. Its unusual for a school of this size.. Trewin, who earned her Ph.D. at UW-Milwaukee, did her undergraduate work at UWP. Cadavers would have facilitated learning, had they been available, said Trewin. They provide hands-on, real world experience.. Weber and Trewin, who worked with College of Business, Industry, Life Science and Agriculture ...
Eugène Dubois was born in the Dutch city of Eijsden, into the family of Jean Joseph Balthasar Dubois and Maria Catharina Floriberta Agnes Roebroeck. Dubois father, a pharmacist, encouraged his sons interest in natural history. At that time, important scientific progress had been made in the world of archaeology and anthropology: in Germany, the remains of an early hominid (later named Neanderthal) were found in the Neander Valley, and Charles Darwin had just published his The Origin of Species.. Dubois was an excellent student, and graduated as a medical doctor in 1884. He married the same year and was appointed a lecturer in anatomy at the University of Amsterdam in 1886. He studied comparative anatomy of the larynx in vertebrates, and soon became an assistant to the Dutch morphologist, Max Furbringer. However, Dubois life then took an unusual change in direction. Probably because of dissatisfaction with his teaching duties and some conflicts with Furbringer, Dubois shifted toward the ...
Edme Vulpian (1826-1887). 1889 illustration of the French neurologist Edme Felix Alfred Vulpian. Vulpian discovered the chromaffin system of the adrenal gland, and studied the action of drugs such as curare, strychnine and nicotine. He taught and researched neurophysiology and in 1862 took over the running of the Salpetriere mental hospital, Paris, France, with fellow neurologist Jean-Martin Charcot. In 1867, he was appointed professor of pathological anatomy at the faculty of medicine and, in 1872, took the chair of experimental and comparative anatomy. - Stock Image C036/0190
Last week in G9 Biology we dissected Fred the Frankenstein Frog to review the functions of the alimentary canal in digestion and discuss comparative anatomy. We compared how the frogs digestive system as similar to our own and how it is different. For example, the frogs teeth have a similar function to our own but a different structure due to the type of food a frog eats. We then discovered the frogs last meal as we followed the frogs digestive system. To extend the dissection, we then looked at the frogs nervous and muscular system. As the frog was still fresh we were able to stimulate the frogs muscles by sprinkling salt on the exposed tissue. The muscles twitched as the salt simulated the muscles as activated nerve fibres would do when the frog was alive. The students were amazed and a little creeped out as the frogs legs twitched (danced) on their own. We will refer back to this dissection when we study the nervous system next year.. ...
The tract put out by Dr. John Howitt of Canada, entitled Evolution not only has very much packed into a small booklet, but also is very helpful. This has already been put out in 15 editions. It is printed in England and is distributed by the International Christian Crusade of Toronto, Ontario, Canada. ... This booklet defines evolution and also discusses theistic evolution. Then it brings in the evidence from comparative anatomy, embryonic recapitulation, geological record. It shows the absence of pre-Cambrian fossils and the absence of intermediate forms. It gives the supposed evolutionary series. In discussing blood precipitation tests, Howitt points out that there is much variation in blood among humans and animals, and the fact that some similarity can be found between the blood of a human and a bat or a whale does not prove anything. Sometimes whole blood from one human to another, even from one close relative to another, can be fatal. This shows how little an argument we can derive from ...

Abstract. Natural populations of Carpinus orientalis Mill. Shrub lands occur mainly in high and middle altitudes of the Hyrcanian forests, N. Iran, particularly on steep rocks and forest outcrops. There are some discrepancies on the intra-specific delimitation of this important woody species. The aim of the current study was to examine the anatomical variation of stems and leaves of sixteen populations of Carpinus orientalis collected in four north and northeastern provinces of Iran for the first time. Also this study show that anatomical characters of stem showed the highest correlation to climatic factors include temperature, altitude and precipitation and midrib anatomical characters did not show any relationship.
Prior to this study, Nanaloricus mysticus was the only species within family Nanaloricidae studied at the myoanatomical level, though a few transmission electron micrographs of the head region of Armorloricus elegans are available in the literature (cf. [12, 20, 25]; see Table 1). The musculature of Nanaloricus sp. described here differs somewhat from that of N. mysticus revealed by ultrastructural examination. For instance, the radial muscles attached to the furcal base of the mouth cone of N. mysticus (see Figure six in [20]) were not found during this study in Nanaloricus sp. Otherwise, the 8 mouth cone retractors found in Nanaloricus sp. seem to correspond to the 8 homonymous muscles found inside the ridges of the mouth cone of N. mysticus, as well as in Pliciloricus enigmaticus, P. pedicularis, P. diva and Rugiloricus doliolius[10, 11, 16, 20].. In the head, N. mysticus possesses 5 inner and 15-24 outer longitudinal muscles (named head retractors) and 2-3 circular muscles surrounding the ...
The Upper Cretaceous (middle-late Campanian) Wahweap Formation of southern Utah contains the oldest diagnostic evidence of ceratopsids (to date, all centrosaurines) in North America, with a number of specimens recovered from throughout a unit that spans between 81 and 77 Ma. Only a single specimen has been formally named, Diabloceratops eatoni, from the lower middle member of the formation. Machairoceratops cronusi gen. et sp. nov., a new centrosaurine ceratopsid from the upper member of the Wahweap Formation, is here described based on cranial material representing a single individual recovered from a calcareous mudstone. The specimen consists of two curved and elongate orbital horncores, a left jugal, a nearly complete, slightly deformed braincase, the left squamosal, and a mostly complete parietal ornamented by posteriorly projected, anterodorsally curved, elongate spikes on either side of a midline embayment. The fan-shaped, stepped-squamosal is diagnostic of Centrosaurinae, however, this ...
Summary Morphologically, the three species of Trichomonas of man are distinct, although T. vaginalis and T. tenax resemble each other more than either resembles T. hominis. T. vaginalis is much the larger, the other two being about the same length. T. vaginalis is more robust in shape and T. tenax is more slender. T. vaginalis and T. tenax normally have a single compound blepharoplast which may occasionally appear as two approximately equal elements. In T. hominis there are characteristically two blepharoplasts of unequal size, the smaller being ventral in position. The oral and vaginal species have regularly four anterior flagella. T. hominis has a variable number, usually four or five, but more characteristically five. One of these is attached to the smaller ventral blepharoplast and the other four to the larger one. The undulating membrane of T. tenax is relatively longer than that of T. vaginalis, although typically less than body length in both and without an extension of the marginal filament into

It is clarifying and invigorating to have a scholar as searching and well-read as Devin Griffiths address the problem of analogy head on. He ambitiously tracks analogy as an evolving mode of thought during the eighteenth and nineteenth centuries, focusing on analogy as a method central to the emerging field of comparative historicism... The Age of Analogy is an impressive book that refuses to shy away from a topic as daunting as analogy just because it threatens to become unwieldy. Griffiths is unusually generous in the alacrity with which he maps the questions that interest him onto a huge range of scholarly fields, including linguistics, mathematics, publishing history, botany, comparative anatomy, astronomy, and musical theory.. ...

Which reveals the reason for any interest in this subject and the motivation behind promoting claims of ancient races of giants: purely religious. And it also illustrates the cause of so much creationist dishonesty: theyll use anything they can and distort and lie about anything they can in order to support their creationist theology, regardless of how false that theology is.. Other participants here have already pointed out much of this. In Message 7 Sci Cat shows someone holding an elephant femur when looks very similar to a human femur (except its much thicker as expected from that comparative anatomy page quoted above). The origin of many fantastic giant beasts and human giants in ancient mythology was undoubtedly finding such bones. In Message 6 Coyote points out that all search hits on race of giants are on religious sites. In Message 4 Phat, a Christian, points out that there is a lot of fake information on the Internet and that you must be wary of it. In Message 9 Taq mentions the ...
Born at Mechlin, Belgium, 19 Dec., 1809; died at Louvain, 8 Jan., 1894. Educated for the medical profession, he was appointed curator of the natural history museum at the University of Louvain in 1831. Five years later he became professor of zoology and comparative anatomy in the Catholic University at Louvain. This chair he held until the time of his death. He was thus able to celebrate the jubilee of his appointment to his chair and the occasion was duly honoured both in his native and his university cities. Throughout his life he was a most diligent worker, and the list of his contributions to scientific periodicals amounts to over two hundred papers. In the earlier part of his career he directed his attention especially to invertebrates and particularly to marine invertebrates, which he studied during many vacations spent at Ostend. In 1843 he established at his own expense a marine laboratory and an aquarium for the further prosecution of these studies, and this institution is believed to ...
Hadrosaurid dinosaurs, dominant Late Cretaceous herbivores, possessed complex dental batteries with up to 300 teeth in each jaw ramus. Despite extensive interest in the adaptive significance of the dental battery, surprisingly little is known about how the battery evolved from the ancestral dinosaurian dentition, or how it functioned in the living organism. We undertook the first comprehensive, tissue-level study of dental ontogeny in hadrosaurids using several intact maxillary and dentary batteries and compared them to sections of other archosaurs and mammals. We used these comparisons to pinpoint shifts in the ancestral reptilian pattern of tooth ontogeny that allowed hadrosaurids to form complex dental batteries. Comparisons of hadrosaurid dental ontogeny with that of other amniotes reveals that the ability to halt normal tooth replacement and functionalize the tooth root into the occlusal surface was key to the evolution of dental batteries. The retention of older generations of teeth was driven by
I have written about quadrupedal launch on other web resources previously, so I wont belabor the point here. In short, takeoff acceleration in animals tends to be generated mostly by the walking limbs, rather than the wings. As such, takeoff is really a form of running or leaping (usually the latter). The strengths of the limb bones in bending and torsion, particularly with regards to the moments sustained for leaping, are therefore highly indicative of launch mode. Pterosaurs turn out to be much more bat-like in this regard than bird-like: they had forelimbs which were much stronger than the hind limbs across a wide range of body sizes. By contrast, large birds have stronger hind limb elements (particularly the femur) when compared with the forelimb elements. Giant pterosaurs, such as Quetzalcoatlus, had very long, thin hind limb elements, which argues against a bird-like launch. However, because pterosaurs walked on their folded wings, as well, the incredibly robust forelimb musculature and ...
A preliminary step to uncovering evolutionary relationships between fossil populations is to describe and understand the extent of morphological variation that exists within the fossil record. My primary research interest lays in reconsidering the genus Homo fossil record morphological diversity in order to provide a reassessment of the debated classification of the genus.. More specifically, I am interested in testing the validity of hominin taxa which are relevant to the understanding of key moments of the evolutionary history of our genus.. For instance, I have been working on the validity and definition of Homo heidelbergensis Schoetensack, 1908 a key palaeoanthropological species to the understanding of the common origin of Neandertals and Modern Humans. The species was invented after the discovery of the Mauer mandible (Heidelberg, Germany) and has been used to refer to a possible last common ancestor to both species. I used comparative morphology along with phenetic approaches (numerical ...

The basic idea behind body armor hasnt changed very much in the past few thousand years. First, armor stops weapons or projectiles from reaching a persons body. Second, it diffuses the weapons energy so that the final impact causes less damage. While its not effective in every situation, armor can generally help protect people from serious injury or death, especially against the right weaponry.. Over the years, people have had to develop stronger and more advanced armor to protect against increasingly sophisticated weapons. However, in spite of these improvements, modern body armor still has some of the same shortcomings as ancient forms of armor. Whether its made from metal plates or layers of fabric, armor is often heavy and bulky. Many types are rigid, so theyre impractical for use on arms, legs and necks. For this reason, medieval suits of plate armor had gaps and joints to allow people to move around, and the body armor used today often protects only the head and torso.. -One of the ...

The study of the last hadrosaurs that lived in the Iberian Peninsula has been possible thanks to the discovery by the Aragosaurus-IUCA Group of the University of Zaragoza, led by Jose Ignacio Canudo, of the first articulated hadrosaur skull found in southern Europe, from the archeological sites of Arén, in Huesca, Spain. The skull belongs to an Arenysaurus ardevoli, a lambeosaurine (hadrosaur with a hollow cranial crest), whose description was recently published in the French journal Comptes Rendus Palevol, and was part of the Spanish fossil record. According to paleontologists, the new lambeosaurine lived between 65.5 and 68 million years ago, had a very prominent frontal dome, and its biogeographical relationships suggest a paleobiogeographical connection between Asia and Europe during the Late Cretaceous.. Researchers have found, in addition to the partially articulated skull, the mandibular remains and postcranial elements such as vertebrae, girdle and limb bones.. The Spanish ...

Then we have Manuscript B: the dreaded undergrad thesis. I have been working on this thing for a few years, and I really want to see it through, but its getting harder and harder to stay motivated. Its on something completely unrelated to what Im working on now (I looked at skull morphology in Centrosaurus to be exact), which makes it hard. Ive started working on it again, and I need to re-learn all the ceratopsian skull terminology. Met with my former supervisor and co-author last week, and he decided that I need to do a phylogenetic analysis, which Ive never done before outside of an assignment. Thanks to Andy Farke, I have a matrix to work with, and Im slowly combining a few different matrices. Im slowly learning how annoying it is when people use slightly different characters (like one paper uses one character as 0-75% and others use 0-80%. Why you have to be so difficult!), or switch around the character states. All in all, its not too bad, just time consuming ...

This page describes the best practices and guidelines for using EQ syntax to consistently and accurately represent phenotypes from the systematic literature. The guidelines are an evolving set of standards created to improve annotation consistency for the use cases and goals of the Phenoscape project. We provide examples of character types commonly encountered in the systematics literature, and provide discussion of special cases and issues in their annotation. The Entity-Quality (EQ) formalism combines Entity terms from an anatomical ontology, in our case [http://uberon.github.io/ Uberon], with Quality descriptors from the Phenotype and Trait Ontology (PATO). Spatial and positional terms from the Biological Spatial Ontology (BSPO) are also used to represent phenotypes. == PATO terms used to annotate systematic characters == Below is a simplified graph showing a subset of quality terms from the [http://obofoundry.org/wiki/index.php/PATO:Main_Page Phenotype and Trait Ontology (PATO)] used to ...

The equipping of the legions was only partially complete when the Horus Heresy broke out. Many of the Legions that had just been fully equipped with Mark IV armour turned against the Imperium while many of the loyal Legions had been deliberately starved of access to it and remained operating with the older Mark II and Mark III armour. Additionally, even the Legions equipped with Mark IV suits quickly found themselves low on spare parts and unable to manufacture replacement units. With war damage and mobile operations, resupply for damaged equipment was difficult or impossible. Marine artificers and Techmarines had to use old style equipment from older models to keep the legions fighting, as well as salvage from slain enemies and unorthodox innovations of their own.[1][8] This ad-hoc assemblage of various armour mark segments (including new or unoffical design elements) being created by a multitude of legions resulted in an entirely new mark of armour being accidentally created; these ...
